I To all uri/.ioni "it Ima?,I concern:

3e it known that l, li'nomn Couriel:- s'nri'n, a citizen of thalnited States. and a. resident of thecity of St.' Louis and State of i ssouri. have invented a new and useful Ainp'ro.r-firent in Bed-Bottom Fabrics, of which the following isa specification. l

This in fention relates to bed bottom fabrics of tlvat type which comprises strands inadc up o'- interhooked irire units or links and connected at their ends to the side rails ofI the frame b v helical springs, the respective adjacent strands being connected at intervals by transverse units or links.

The invention has for its principal.' ob'- `iects the production of a bed bottom possessing the requisite flexibility 'and spring duality andl adapted for either folding or non-folding bed bottoni frames, and Whose units remain in their true relative positions whether the fabric is under tension or loose.

/ Other advantages to be attainedv Will here# inaft er more fully appeal'. The inven tion consists in the partsand in the arrangements and combinations ofparts hereinafter'described and claimed.l

drawing which' ln the 'accompanying forms part of this specification and wherein like symbols refer to like' parts Wherever tliey-foccur.--Figure l is a fragmentary plan vieu' showing 4an adaptation of the invenA tion in a bed bottom fabricapplied to a non-folding bed bottom frame; and Fig. 2

is a detail view showing cooperating ton- 'Sion strand and transverse units detached.v

The bed bottom frame shown in the dravving comprises longitudinal side rails 1 rigidly attached at their ends to end rails-2, the former being tubular and the latter' of angle iron section.` The fabric comprises tension strands connected at their ends to the end i ils 2 by helical springs Each of thev strands is made up of units or links 4. of Wire. is looped. as-at. 5 sides, as at 6. the l'ialance of the Wire then 4ent-ending straight in ara`llel relation and havinOr evcs 7 formed at its ends. The iar- V C 'l' l allel portions .of the link are preferably arranged approximately .in line with the centersnof the loops G so that; when the respective units are joined the straight parallel portions are in line. .Thus a double strand is provided Whosel individual strands have a straight pull. v

'At one end the strands'may be conven- -opposite ends of through said i overlapping loops lqucntly, the links The middle portion of the Wire and relooped lon opposite adjoining strandluni strands together,

the loops. of the springs through said loops.

7. The connection With the springs at the the respective strands may be effected by bringing the parallel portions of the endmost units together adjacent to the .loops 5 and making the 'pair of loops G overlap, as shown to the right in Fig. .1, and hooking the loops of the springs vThe tension strands are connected by transverse iv-ire linksS having eyes 9 at their ends which are engaged in the respective loops of 'adjacent tension strand units. It is to be understood that the eyes 9.of the links 8 .should be of -no Vgreater .diameter `than that of the loops 6 of the tension stran'd units, but preferably of a diameter slightly' less, so that When said eyes 9 are engaged in the loops they cannot be passed .overthe,loops 6. Con-se' or units will .not move out of their true relative positions. The transverse links Shaving their loops 9 eligaged with the loops 5 of the strandl units prevent the looped portions. 7 of one strand unit from passing between the-loop 5 and 'parallel .portion of the adjoining strand unit. It.- is obvious, therefore,"that` thelinks or units ofthe vfabric cannot become tangled under any circumstances andthe structure 'possesses that'exibility which permits the fabric Vto be readily rolled Vor folded, thereby making it Well adapted for folding couches as VWell as non-folding bed bottom frames. i i

Obviously, the fabric admitsof consider| able modification Without departing from 'the invention. Therefore, I do not. Wish to be limitedfto the specific construction and arrangement shown. y
